Question

When a liquid is taken in a container Choose the correct option
a- The pressure inside the liquid increasing with depth.
b- The pressure inside a liquid at depth h is given by P= po. + p1gh
c- The pressure inside the liquid at a constant depth is constant.
d- All of the above





Answer Please
Thank you in advance ​

Answer 1

Option (d) is the correct option

Explanation:

• Pressure inside a liquid at a constant depth will be a constant value. This happens because pressure inside a liquid is gien by P = hdg ( where h is the depth of liquid in the container , d is the density and g is acceleration due to gravity ). If we consider the depth as constant , the pressure will also remain constant as per the given equation above. Therefore statement (c) is correct.
• Statement (b) also a result of Pascal's law , is correct $P = P_o + p_1gh$ , where $P = P_o + p_1gh$ , where $p_1$ is the density. Statement (b) is also correct.
• The pressure inside the liquid increases with increasing depth. As the depth is increased, the weight of liquid exerting pressure , increases. Also as per the equation mentioned above , as height or depth is increases, the pressure is also increased. Statement (a) is correct.
• Therefore all the statements are correct.
